Well this is kind of interesting.

High coffee intake tied to lower prostate cancer risk - Health - CBC News

men who consumed coffee regularly had a reduced risk of lethal or advanced prostate cancer

Men who consumed the most coffee — six or more cups daily — had 0.82 times the risk of developing any form of prostate cancer.

Men who drank the most coffee had a 0.40 times lower risk of developing lethal prostate cancer.

The reduction in risk occurred whether men drank decaffeinated or regular coffee, and does not appear to be due to caffeine.

Coffee drinkers were more likely to smoke and less likely to exercise, lifestyle factors that were taken into account in estimating the risk reduction from the drink.

The link between drinking coffee and lower risk of advanced prostate cancer is biologically plausible, the researchers said. Coffee contains many beneficial compounds with antioxidant and anti-inflammatory effects and affect sex hormone levels, all of which they said may influence prostate cancer.

Three caveats, of course
- They had to adjust for heavy coffee-drinkers' other risk factors, you'd want to know how conservatively that was done
- What other effects does coffee have, that are negative? Anyone know? HBP?
- No statistical significance indicated in the news story.
